Inclined screen tray tower

Abstract

An inclined screen tray tower having one or more inclined screen trays, in which a liquid is passed downwardly onto said screen tray to form a film of said liquid on each of said screens and gas is passed through said liquid films so as to be absorbed by said liquid, characterized in that a plurality of cylinders are arranged side by side on each of said tray screens in such a manner that the longitudinal axis of each of said cylinders extends in the direction of inclination of each of said tray screens, each of said cylinders being made of a netting with metallic or synthetic resinous wires each arranged to make an angle of about 45 DEG with the longitudinal axis of said cylinders.

We claim: 
     
       1. An inclined screen tray tower having one or more inclined screen trays, in which a liquid is passed downwardly onto said screen tray to form a film of said liquid on each of said screens and gas is passed through said liquid films so as to be absorbed by said liquid, characterized in that a plurality of cylinders are arranged side by side on each of said tray screens in such a manner that the longitudinal axis of each of said cylinders extends in the direction of inclination of each of said tray screens, each of said cylinders being made of a netting with metallic or synthetic resinous wires each arranged to make an angle of about 45° with the longitudinal axis of said cylinders. 
     
     
       2. An inclined screen tray tower according to claim 1, wherein the angle of inclination of said screen tray is in the range between 5° and 20°, and wherein each said screen is a screen of 5 to 20 meshes according to the Tyler standard screen scale. 
     
     
       3. An inclined screen tray tower according to claim 2, wherein each said cylinder is made of a screen having a wire pitch in the range between 5 and 15 mm, and wherein each said cylinder has a diameter in the range between 30 and 70 mm.
